First off, I'm a little confused as to how the helper option for
draggables works. Right now I'm just using the default value and
everything works great, but its not quite what I wanted visually.
Ideally, I would like to display a medium sized, plain, file icon
image that has a number in it when a file in my directory listing
script is being dragged. Here is the code I am using so far:
$('.file').draggable({
    cursor: 'pointer',
    opacity: 0.5,
    revert: 'invalid',
    delay: 150
});
If anyone could give some example code of a helper, that would be much
appreciated. The docs seem to be lacking this unfortunately, and I'm
not entirely sure what they mean by a "DOM node".
